Experiencing a finicky key fob for your 2008 Volvo S40? Before you jump to conclusions about needing a whole new one, it’s highly likely that the culprit is simply a drained battery.

We’ll walk you through the process, offering clear instructions and helpful tips to get you back on the road with a click of a button.
How to Identify a Dying Key Fob Battery
Let’s face it, our cars are pretty good at giving us warning signs if something is amiss. Key fobs are no different. Here are some telltale signs that your 2008 Volvo S40 key fob battery is nearing its end:
- Decreased Range: Notice you have to be practically touching your car door for the key fob to work? That’s a classic sign of a weakening battery.
- Intermittent Functioning: One minute it works, the next it doesn’t – this inconsistency is a surefire sign that your key fob battery needs attention.
- Warning Light on Dashboard: Some Volvo models will even display a warning message on your dashboard, like “Key Battery Low”, to give you a heads up.
What You’ll Need for the Replacement
The good news is you won’t need a mechanic or any fancy tools for this job. Here’s what you’ll need to gather:
- New Battery: A CR2032 battery. These are readily available online or at any electronics or auto parts store.
- Small Flathead Screwdriver: This will help you gently pry open the key fob casing.
